Stefan Richter commented on FLINK-8413: --------------------------------------- Can you share a (minimal) code example that shows this problem? > Snapshot state of aggregated data is not maintained in flink's checkpointing > ---------------------------------------------------------------------------- > > Key: FLINK-8413 > URL: https://issues.apache.org/jira/browse/FLINK-8413 > Project: Flink > Issue Type: Bug > Components: State Backends, Checkpointing > Affects Versions: 1.3.2 > Reporter: suganya > > We have a project which consumes events from kafka,does a groupby in a time > window(5 mins),after window elapses it pushes the events to downstream for > merge.This project is deployed using flink ,we have enabled checkpointing to > recover from failed state. > (windowsize: 5mins , checkpointingInterval: 5mins,state.backend: filesystem) > Offsets from kafka get checkpointed every 5 > mins(checkpointingInterval).Before finishing the entire DAG(groupBy and > merge) , events offsets are getting checkpointed.So incase of any restart > from task-manager ,new task gets started from last successful checkpoint ,but > we could'nt able to get the aggregated snapshot data(data from groupBy task) > from the persisted checkpoint. > Able to retrieve the last successful checkpointed offset from kafka ,but > couldnt able to get last aggregated data till checkpointing. -- This message was sent by Atlassian JIRA (v6.4.14#64029)
